To all whom it may concern,.-

Be it known that we, MELVIN E. HASKINS and GEORGE L. EVANS, citizens of the United Y reference to be operated bya stream of water from a iiume or sluiceway, the said wheel being vertically disposed and operating without being incased, In the improved form oi' wheel the wings extend in radial lines from the hub or axial lin'e, the outer ends being provided with flanges which curve in cross-section` to correspond with the circular outline of the wheel and which gradually diminish in width from the receiving to the discharging end of the wheel. Short supplemental blades are disposed at the receiving end of the wheel, and are secured at their inner edges to the wings, their outer edges terminating a short distance from the flanges of their respective supporting-wings, and the said blades being disposed at approximately an intermediate point between the hub and outer flanges of the said Wheel. These short blades curve in their length, and occupy a position approximately parallel with the free edges of the anges provided at the outer edges of the wings supporting the respective blades.

For a full understanding of the invention reference is to be had to the following description, taken in connection with the accompanying drawings, in which- Figure l is a perspective view of a waterwheel embodying the essential principles of theinvention. Fig. 2 is a top plan view of the same. Fig. 3 is a view similar to Fig. 1, having the flanges on the near side broken away.

The wheel comprises, essentially, the hub l, wings 2, having the anges 3 at their outer edges, and the short supplemental blades 4. The wings 2, which may be provided in any desired number, extend in radial lines from the hub l and appear as straight lines in plan elevation or in plan section taken at any point in the length of the wheel. These wings 2 occupy an approximately spiral position relative to the length of the wheel, in the usual manner, so as to impart, a rotary movement to the Wheelon impact of the watertherewith. The flanges 3 curve to correspond with the circular outline of the wheel, as shown most clearly in Fig. 2, and gradually diminish in width from the receiving to the discharge end of the wheel, as plainly indicated in Fig. l. These flanges serve to retain the water in contact with the wings 2, so as to attain the best possible results and the greatest power from the head of the water. The short supplemental blades 4 are disposed at the receiving end of the wheel, and are secured at their inner edges to the wings 2. The length of these blades will depend upon the nature of the wheel, and the peculiar conditions for which the same is designed. Usually they will be about one-third the length of the wheel. Obviously, the dimensions will vary according to the design and work for which the wheel is especially constructed. The blades 4 occupy a position midway between the hub and the iiangcs 3, and have their outer edges terminate a short distance from the circular outline of the wheel, so as to provide an escape 5 between their outer edges and the adjacent edges of the [ianges 3. These blades curve in their length, and occupy aposition approximately parallel with the edges ofthe flanges 3, carried by the wings to which the respective blades are attached. The blades 4, in conjunction with the opposing flanges 3, confine the Water at the receiving end of the Wheel in such a manner as to attain the best possible results and the maximum amount of power from the descending stream. The blades being disposed at the receiving end prevent the outward splashing of the water when it first comes in contact with the wheel and serve to maintain the same in a compact body, so as to secure the greatest amount of force from a given head and bulk of stream.

In the operation of the invention the wheel will be vertically disposed and arranged beneath a stream of water descending from a -tlume or other water-way, and the power is derived from its shaft in any desired and convenient manner.

In the organization and disposition of the parts of the wheel changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what We claim isl. A water-wheel having its wings disposed in straight radial lines and having curved iian ges at their outer edges, said Hanges gradually diminishing in Width from the receiving to lthe discharging end of the wheel, and short blades carried by the wings and disposed at an intermediate point between the hub and flanges, and extending and curving in their length to correspond with the curved edges of the said flanges, substantially as set forth.

2. The herein shown and described Waterwheel composed of a plurality of Wings extending in straight radial lines from the hub and running spirally in the direction of their length, and having curved flanges at their zo outer edges which gradually diminish in width from the receiving to the discharging end of the Wheel, and short blades attached to one face of the wings and occupying an intermediate position between the hub and the adjacent anges, the outer edges of the blades terininating a short distance froin the circular outline of the wheel and extending approximately parallel with the free edges ot' the adjacent flanges, substantially as set forth.

In testimony that We claim the foregoing as our own We have hereto a'l'ixed our signatures in the presence of two witnesses.
